About rip currents

This summer, the National Oceanic and Atmospheric Administration
and the National Weather Service began a media awareness
campaign about the dangers of rip currents on the country's
coasts and Great Lakes.
Rip currents are the leading safety threat to beach goers,
according to the U.S. Lifesaving Association.
A rip current happens when strong wind and high waves
perpendicular to shore push water over the sandbar, allowing
excess water to collect. The weight of the accumulating
water near the shore then "rips" an opening
in the sandbar, creating a narrow underwater river that
catapults everything in its path out into the lake.
More detailed information on what creates rip currents
and how to escape one is available on the Web site for
the National Weather Service in Duluth: www.ripcurrents.noaa.gov.
